A possible person of interest in the May 8 slaying is wanted for questioning, police said Tuesday at a news conference at the Baytown Police Department.

A sketch released shows a young man wearing a black hoodie. A recently discovered witness described him as more than 6 feet tall with a slim build.

The day of the crime, Shal's husband of nine years, David Englerth, was out of town. He called police because he'd been unable to reach his wife by phone and wanted officers to do a welfare check.

When police showed up just before 10 p.m. at the Lakes of Madera Apartments on West Baker, they peered in a window and caught a glimpse of Shal's lifeless body.

Officers forced their way through a locked door to discover the mother of one, brutally slain.

"She's the only woman I've ever loved, period," Englerth said, tearing up at the news conference.

The couple met in Prague in 2003, when Englerth was in the military. They married four years later.

"She put up with me for 13 years - and I'm not an easy person to get along with," he said.

An accomplished businesswoman born in Ukraine, Shal spoke seven languages.

"I admired her and I loved her," the grief-stricken husband said.

When police released a sketch of the man who was seen around the apartment on the day of the crime, they emphasized that he is not considered a suspect at this time.

"We are asking for the public's help in identifying and locating this person of interest, as well as any information that would help us solve this crime and help the family of Ms. Shal start the healing process," Lt. Steve Dorris said.

There's still no word on a motive and police declined to release details about the crime, citing the integrity of the investigation.

Baytown Crime Stoppers has increased the reward from $5,000 to $25,000, Dorris said.
